Depending on the level of pain and damage suffered by a patient, a physician will recommend a treatment regimen that will relieve symptoms. Some of the most common recommendations include avoiding activities that make the pain worse, ice the knee for 20 to 30 minutes throughout the day to reduce inflammation, use over the counter anti-inflammatory medications, paracetamol (acetaminophen) and physical therapy.
Topical creams and patches can also be used for pain treatment and they have been proven to reduce pain by 33 to 57%.
Exercises can help increase range of motion and flexibility as well as help strengthen the muscles in the leg. Physical therapy and exercise are often effective in reducing pain and improving function. Working with a physical therapist to find exercises that promote function without risking further injury is effective for most patients. Many of the exercises used can be performed while sitting in a chair or standing in place. They are performed so that additional stress or weight is not placed on the knee joint. Water exercises are highly recommended along with the use of elastic bands.
Supportive devices like knee braces can be used. In most cases, the arthritis is centered on a single side of the knee, so braces are effective in providing stability to one side. Two different forms of braces are available. A support brace provides the aid the entire knee requires, where an up-loader brace shifts the pressure away from the specific part of the knee that is experiencing the pain. Shoes or inserts that are considered to be energy absorbing are found useful for some patients as well as walking devices like a cane. Shoe insoles that are fitted to correct flat feet have provided relief to many patients.
The use of oral steroids and anti-inflammatory medicines help to reduce the amount of inflammation and pain felt in the knee. If over the counter medicines like ibuprofen or naproxen are not strong enough, prescription strength medicines are used. If oral medicine and physical therapy don't help your knee enough, doctors may consider giving patients injections with pain medicine. Hyaluronic acid is present in the knee, but injections of it can be used to protect the joint when the cartilage becomes thinner and can't do it alone. These injections can provide more pain relief than oral medications lasting from six months to a year.
Surgery is the final option but may be required to relieve symptoms. Arthroscopy is performed through tiny cuts where damaged parts of the knee can be removed. Osteotomy is performed to reshape the bones in the knee and is only performed if one side of the knee is damaged. Arthroplasty is a replacement surgery where an artificial joint is used.
Low level laser therapy can be considered for relief of pain and stiffness associated with osteoarthritis.
The pain medication acetaminophen is the first line treatment for osteoarthritis. However, a 2015 review found acetaminophen to only have a small short-term benefit. For mild to moderate symptoms effectiveness is similar to non-steroidal anti-inflammatory drugs (NSAIDs), though for more severe symptoms NSAIDs may be more effective. NSAIDs such as naproxen, while more effective in severe cases, are associated with greater side effects, such as gastrointestinal bleeding. Diclofenac may be the most effective NSAID.
Another class of NSAIDs, COX-2 selective inhibitors (such as celecoxib) are equally effective when compared to nonselective NSAIDs, and have lower rates of adverse gastrointestinal effects, but higher rates of cardiovascular disease such as myocardial infarction. They are also more expensive than non-specific NSAIDs. Benefits and risks vary in individuals and need consideration when making treatment decisions. NSAIDS applied topically are effective for a small number of people.
Failure to achieve desired pain relief in osteoarthritis after 2 weeks should trigger reassessment of dosage and pain medication. Opioids by mouth, including both weak opioids such as tramadol and stronger opioids, are also often prescribed. Their appropriateness is uncertain, and opioids are often recommended only when first line therapies have failed or are contraindicated. This is due to their small benefit and relatively large risk of side effects. Oral steroids are not recommended in the treatment of osteoarthritis.
There are several NSAIDs available for topical use, including diclofenac. A Cochrane review from 2016 concluded that reasonably reliable evidence is available only for use of topical diclofenac and ketoprofen in people aged over 40 years with painful knee arthritis. Transdermal opioid pain medications are not typically recommended in the treatment of osteoarthritis. The use of topical capsaicin to treat osteoarthritis is controversial, as some reviews found benefit while others did not.
Joint injection of glucocorticoids (such as hydrocortisone) leads to short term pain relief that may last between a few weeks and a few months. Injections of hyaluronic acid have not produced improvement compared to placebo for knee arthritis, but did increase risk of further pain. In ankle osteoarthritis, evidence is unclear. The effectiveness of injections of platelet-rich plasma is unclear; there are suggestions that such injections improve function but not pain, and are associated with increased risk. A 2015
A 2015 Cochrane review found that intra-articular corticosteroid injections of the knee did not benefit quality of life and had no effect on knee joint space; clinical effects one to six weeks after injection could not be determined clearly due to poor study quality. Another 2015 study reported negative effects of intra-articular corticosteroid injections at higher doses, and a 2017 trial showed reduction in cartilage thickness with intra-articular triamcinolone every 12 weeks for 2 years compared to placebo.
While acupuncture leads to improvements in pain relief, this improvement is small and may be of questionable importance. Waiting list-controlled trials for peripheral joint osteoarthritis do show clinically relevant benefits, but these may be due to placebo effects. Acupuncture does not seem to produce long-term benefits. While electrostimulation techniques such as TENS have been used for twenty years to treat osteoarthritis in the knee, there is no conclusive evidence to show that it reduces pain or disability.
A Cochrane review of low level laser therapy found unclear evidence of benefit. Another review found short term pain relief for osteoarthritic knees.
Treatment of fluid in the knee depends on the underlying cause of the swelling. General measures such as rest, ice, and analgesics such as acetaminophen (paracetamol) and NSAIDS are often recommended. Chymotrypsin, trypsin and Diclofenac are also recommended.
Treatment consists of rest, non-weightbearing and painkillers when needed. A small study showed that the nonsteroidal anti-inflammatory drug ibuprofen could shorten the disease course (from 4.5 to 2 days) and provide pain control with minimal side effects (mainly gastrointestinal disturbances). If fever occurs or the symptoms persist, other diagnoses need to be considered.
Although surgery has a role in repairing traumatic injuries and broken bones, surgeries such as arthroscopic lavage do not provide significant or lasting improvements to either pain or function to people with degenerative knee pain, and therefore should almost never be performed. Degenerative knee pain is pain caused by wear and tear, such as osteoarthritis or a meniscal tear. Effective treatments for degenerative knee pain include physical therapy exercises, pain-reducing drugs such as ibuprofen, knee replacement surgery, and weight loss in people who are overweight.
No treatment has been found to be routinely effective. NSAIDs and COX-2 inhibitors are not generally helpful other than for general pain relief. They do not seem to help reduce effusions or prevent their occurrence. Low-dose colchicine (and some other ‘anti-rheumatic’ therapies e.g. hydroxychloroquine) have been used with some success. (Use of methotrexate and intramuscular gold have not been reported in the literature). More aggressive treatments such as synovectomy, achieved using intra-articular agents (chemical or radioactive) can provide good results, with efficacy reported for at least 1 year.
Reducing acute joint swelling:
Arthrocentesis (or drainage of joint) may be useful to relieve joint swelling and improve range of motion. Local steroid injections can also reduce fluid accumulation short-term, but do not prevent onset of episodes. These treatments provide temporary relief only. Bed rest, ice packs splints and exercise are ineffective.
A single case report of a patient with treatment-refractory IH describes the use of anakinra, an interleukin 1 receptor antagonist. At the first sign of any attack, a single 100 mg dose was given. With this dosing at onset of attacks, each episode of effusion was successfully terminated.
Reducing frequency and severity of IH episodes:
Case reports indicate some success using long-term, low-dose colchicine (e.g. 0.5 mg to 1 mg daily). A recent single case report has shown hydroxychloroquine (300 mg daily) to be effective too.
Small-sized clinical trials have shown positive results with (1) chemical and (2) radioactive synovectomy. (1) Setti et al. treated 53 patients with rifampicin RV (600 mg intra-articular injections weekly for approximately 6 weeks) with good results at 1 year follow-up. (2) Top and Cross used single doses of intra-articular radioactive gold in 18 patients with persistent effusions of mixed causes including 3 with IH. All 3 patients with IH responded well to treatment at one-year follow-up.
The major types of medications used to treat ankylosing spondylitis are pain-relievers and drugs aimed at stopping or slowing the progression of the disease. All of these have potentially serious side effects. Pain-relieving drugs come in two major classes:
- The mainstay of therapy in all seronegative spondyloarthropathies are anti-inflammatory drugs, which include NSAIDs such as ibuprofen, phenylbutazone, diclofenac, indomethacin, naproxen and COX-2 inhibitors, which reduce inflammation and pain. Indomethacin is a drug of choice. 2012 research showed that those with AS and elevated levels of acute phase reactants seem to benefit most from continuous treatment with NSAIDs.
- Opioid painkillers
Medications used to treat the progression of the disease include the following:
- Disease-modifying antirheumatic drugs (DMARDs) such as sulfasalazine can be used in people with peripheral arthritis. For axial involvement, evidence does not support sulfasalazine. Other DMARDS, such as methotrexate, did not have enough evidence to prove their effect. Generally, systemic corticosteroids were not used due to lack of evidence. Local injection with corticosteroid can be used for certain people with peripheral arthritis.
- Tumor necrosis factor-alpha (TNFα) blockers (antagonists), such as the biologics etanercept, infliximab, golimumab and adalimumab, have shown good short-term effectiveness in the form of profound and sustained reduction in all clinical and laboratory measures of disease activity. Trials are ongoing to determine their long-term effectiveness and safety. The major drawback is the cost. An alternative may be the newer, orally-administered non-biologic apremilast, which inhibits TNF-α secretion, but a recent study did not find the drug useful for ankylosing spondylitis.
- Anti-interleukin-6 inhibitors such as tocilizumab, currently approved for the treatment of rheumatoid arthritis, and rituximab, a monoclonal antibody against CD20, are also undergoing trials.
- Interleukin-17A inhibitor secukinumab is an option for the treatment of active ankylosing spondylitis that has responded inadequately to (TNFα) blockers.
In the absence of cartilage damage, pain at the front of the knee due to overuse can be managed with a combination of RICE (rest, ice, compression, elevation), anti-inflammatory medications, and physiotherapy.
Usually chondromalacia develops without swelling or bruising and most individuals benefit from rest and adherence to an appropriate physical therapy program. Allowing inflammation to subside while avoiding irritating activities for several weeks is followed by a gradual resumption. Cross-training activities such as swimming, strokes other than the breaststroke, can help to maintain general fitness and body composition. This is beneficial until a physical therapy program emphasizing strengthening and flexibility of the hip and thigh muscles can be undertaken. Use of nonsteroidal anti-inflammatory medication is also helpful to minimize the swelling amplifying patellar pain. Treatment with surgery is declining in popularity due to positive non-surgical outcomes and the relative ineffectiveness of surgical intervention.
Once PVNS is confirmed by biopsy of the synovium of an affected joint, a synovectomy of the affected area is the most common treatment. Bone lesions caused by the disorder are removed and bone grafting is performed as needed. Because diffuse PVNS has a relatively high rate of recurrence, radiation therapy may be considered as a treatment option. In some cases, a total joint replacement is needed to relieve symptoms when PVNS causes significant joint destruction.
There are several types of medications that are used for the treatment of arthritis. Treatment typically begins with medications that have the fewest side effects with further medications being added if insufficiently effective.
Depending on the type of arthritis, the medications that are given may be different. For example, the first-line treatment for osteoarthritis is acetaminophen (paracetamol) while for inflammatory arthritis it involves non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Opioids and NSAIDs are less well tolerated.
Rheumatoid arthritis (RA) is autoimmune so, in addition to pain medications and anti-inflammatory drugs, is treated with another category of drug called disease-modifying antirheumatic drugs (DMARDs), which act on the immune system to slow down the progression of RA. An example of this type of drug is methotrexate.
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat PFPS, however there is only very limited evidence that they are effective. NSAIDs may reduce pain in the short term, overall however, after three months pain is not improved. There is no evidence that one type of NSAID is superior to another in PFPS, and therefore some authors have recommended that the NSAID with fewest side effects and which is cheapest should be used.
Glycosaminoglycan polysulfate (GAGPS) inhibits proteolytic enzymes and increases synthesis and degree of polymerization of hyaluronic acid in synovial fluid. There is contradictory evidence that it is effective in PFPS.
Medication is not the primary treatment for hypermobility, but can be used as an adjuct treatment for related joint pain. NSAIDS are the primary medications of choice. Narcotics are not recommended for primary or long term treatment and are reserved for short term use after acute injury.
There is no cure for AS, although treatments and medications can reduce symptoms and pain.
Non-septic prepatellar bursitis can be treated with rest, the application of ice to the affected area, and anti-inflammatory drugs, particularly ibuprofen. Elevation of the affected leg during rest may also expedite the recovery process. Severe cases may require fine-needle aspiration of the bursa fluid, sometimes coupled with cortisone injections. However, some studies have shown that steroid injections may not be an effective treatment option. After the bursitis has been treated, rehabilitative exercise may help improve joint mechanics and reduce chronic pain.
Opinions vary as to which treatment options are most effective for septic prepatellar bursitis. McAfee and Smith recommend a course of oral antibiotics, usually oxacillin sodium or cephradine, and assert that surgery and drainage are unnecessary. Wilson-MacDonald argues that oral antibiotics are "inadequate", and recommends intravenous antibiotics for managing the infection. Some authors suggest surgical irrigation of the bursa by means of a subcutaneous tube. Others suggest that bursectomy may be necessary for intractable cases; the operation is an outpatient procedure that can be performed in less than half an hour.
Treatment is generally conservative with rest, ice, and specific exercises being recommended. Simple pain killers may be used if required such as acetaminophen (paracetamol) or ibuprofen. Typically symptoms resolve as the growth plate closes. Physiotherapy is generally recommended once the initial symptoms have improved to prevent recurrence. Surgery may rarely be used in those who have stopped growing yet still have symptoms.
As patellofemoral pain syndrome is the most common cause of anterior knee pain in the outpatient, a variety of treatments for patellofemoral pain syndrome are implemented. Most patients with patellofemoral pain syndrome respond well to conservative therapy.
Knee MRIs should be avoided for knee pain without symptoms or effusion, unless there are non-successful results from a functional rehabilitation program.
A number of rheumasurgical interventions have been incorporated in the treatment of arthritis since the 1950s. Arthroscopic surgery for osteoarthritis of the knee provides no additional benefit to optimized physical and medical therapy.
One of the main ways to prevent OSD is to check the participant's flexibility in their quadriceps and hamstrings. Lack of flexibility in these muscles can be direct risk indicator for OSD. Muscles can shorten, which can cause pain but this is not permanent. Stretches can help reduce shortening of the muscles. The main stretches for prevention of OSD focus on the hamstrings and quadriceps.
Because any medication that could reduce the inflammation of CPPD bears a risk of causing organ damage, treatment is not advised if the condition is not causing pain.
For acute pseudogout, treatments include intra-articular corticosteroid injection, systemic corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), or, on occasion, high-dose colchicine. In general, NSAIDs are administered in low doses to help prevent CPPD. However, if an acute attack is already occurring, higher doses are administered. If nothing else works, hydroxychloroquine or methotrexate may provide relief.
Research into surgical removal of calcifications is underway, however this still remains an experimental procedure.
Treatment generally includes the following:
- Sometimes pharmacologic therapy for initial disease treatment
- Physical therapy
- Occupational therapy
- Use of appropriate assistive devices such as orthoses
- Surgical treatment
For some people with hypermobility, lifestyle changes decrease symptom severity. In general activity that increases pain is to be avoided. For example:
- Typing can reduce pain from writing.
- Voice control software or a more ergonomic keyboard can reduce pain from typing.
- Bent knees or sitting can reduce pain from standing.
- Unwanted symptoms are frequently produced by some forms of yoga and weightlifting.
- Use of low impact elliptical training machines can replace high-impact running.
- Pain-free swimming may require a kickboard or extra care to avoid hyperextending elbow and other joints.
- Weakened ligaments and muscles contribute to poor posture, which may contribute to other medical conditions.
- Isometric exercise avoids hyperextension and contributes to strength.
JIA is best treated by a multidisciplinary team. The major emphasis of treatment for JIA is to help the child regain normal level of physical and social activities. This is accomplished with the use of physical therapy, pain management strategies, and social support. Another emphasis of treatment is to control inflammation and extra-articular symptoms quickly. Doing so should help to reduce joint damage and other symptoms, which will help reduce levels of permanent damage leading to disability.
Beneficial advances in drug treatment have been made over the last 20 years. Most children are treated with nonsteroidal anti-inflammatory drugs and intra-articular corticosteroid injections. Methotrexate, a disease-modifying antirheumatic drug (DMARD) is a powerful drug which helps suppress joint inflammation in the majority of JIA patients with polyarthritis (though less useful in systemic arthritis). Newer drugs have been developed recently, such as TNF alpha blockers, such as etanercept. No controlled evidence supports the use of alternative remedies such as specific dietary exclusions, homeopathic treatment, or acupuncture. However, an increased consumption of omega-3 fatty acids proved to be beneficial in two small studies.
Celecoxib has been found effective in one study.
Other aspects of managing JIA include physical and occupational therapy. Therapists can recommend the best exercise and also make protective equipment. Moreover, the child may require the use of special supports, ambulatory devices, or splints to help them ambulate and function normally.
Surgery is only used to treat the most severe cases of JIA. In all cases, surgery is used to remove scars and improve joint function.
Home remedies that may help JIA includes getting regular exercises to increase muscle strength and joint flexibility. Swimming is perhaps the best activity for all children with JIA. Stiffness and swelling can also be reduced with application of cold packs, but a warm bath or shower can also improve joint mobility.
In the future, genetic testing may be available allowing earlier detection of JIA. Early detection will help determine the severity of the disease in each child and help identify which therapies will be the most effective and beneficial treatment options.
Early stages may be treated conservatively using the R.I.C.E methods.
1. Rest
2. Ice
3. Compression
4. Elevation
Exercises involving eccentric muscle contractions of the quadriceps on a decline board are strongly supported by extant literature. A physical therapist may also recommend specific exercises and stretches to strengthen the muscles and tendons, eg. cycling or swimming. Use of a strap for jumper's knee and suspension inlays for shoes may also reduce the problems.
Should this fail, autologous blood injection, or platelet-rich plasma injection may be performed and is typically successful though not as successful as high volume saline injection (Crisp "et al."). Uncommonly it may require surgery to remove myxoid degeneration in the tendon. This is reserved for patients with debilitating pain for 6–12 months despite conservative measures. Novel treatment modalities targeting the abnormal blood vessel growth which occurs in the condition are currently being investigated.
New research shows that knee operations in most cases have no better effects than exercise programs, and that most knee operations thus can be avoided.
